Abstract:   (11139 Views)

  UBV photometric observations of Ap star Cyg V1584 have been presented. To find the rotational period of the star, a sinusoidal wave function has been fitted to the noramal points of UBV filters. Assuming that a circular hot spot located at the magnetic pole of the star is responsible for the observed light variations, both physical an geometrical parameters of the spot have been determined. Finally, the angle between the magnetic and the rotational axis has been calculated from combining the spectroscopic and photometric data and the magnetic structure of the star has been discussed.
